' opening and closing a series of windows that have pivotally hungsash. The object ofthe'inventlon 1s to provride such a means which'is simple, there by 1nsuring cheapness of manufacture and installation; which is compact, whereby when installed it occupies but little space and is comparativelyinconspicuous and which is easily operated and yet very powerful in action so it may be manipulated by any one with a certainty that the sash, no matter how many in the series, will be pushed open in unison and drawn, tightly closed when desired.

In attainingthis end chain so con structed that it can be bent in one "directlon only and when fixed at two points becomes between those points rigid in all directions I wherebyendpressure, to any amount within the limit of the strength of the materials, can be applied without having; the chain flex. One of more sections oi such a cha n are connected to each of the. sashltobe opened and to an operating member that-is movably supported parallel with the swinging edges of the sash, so that when this operating member is moved in one directlon the cha ns pushthe sash open "and when the operating member ismoved in the opposite direction the chain's draw the sash. closed.

a side view of a modified arrangement of the operating means.

Each chainlink may be formed of a,

stamped blank 1,-Fig. 8, that is provided with two pivot openings2 at each end, the pivot openings on one edge being offset in one direction, andthe pivotopeningson the other edge being offset in theother direction (as shown in Fig. 9) so that the links will fit together when assembled. These blanks are bent so as to form a link 3which is U- shape in cross section as shown in Fig. 7,

and the links are fastened together by pivot studs'fl; When "the links are thus put together and are in a straight line as in Fig. 6, they form practically achannel iron that will "stand as much end'wise thrust as the strength of: the material will sustain, and this channel can onlybeflexed in one direction (as in Fig. 10). r I

'One end ofa short section of chain thus formed 'may be se'cured to a bracket 5 that is pivoted to ears 6 projecting from a plate -7 whiclrmay be fastened by screws 8, or otherwise, either, to the middle of the cross rail 9 of thewindow sash, as shown in Fig. '1, or the ends of two sections of chain may be fastened bysuch means to the side rails chains are desirably used. Theother end of each section of the chain may be secured to a brackeull and 'tli-is bracket maybe fastened to the inner face ofa channel iron '12 when suclra structureiseniployed as the operating neansl' 'This channel iron extends along the building parallel with the swing; ing edges Q'f all of the sash that are tobe movably held by groovedrollers'13, the rollers being arranged so as to support and fastened-to thecasingloat' the sidesof or.

openedsimultaneously, and it isshown as arms 17' which are mounted on an axle 18.

that is supported by the arms 01 a bracket 19 attached to a bar 20 extending between the brackets 14:. The shoe may asshown in Fig. 3have its inner edges 21 benttoward each other forthe purpose of retaining the a chain within it. If it is desired to have the chain-run a littleeasier a roller'22 maybe located on the inside of the bend of the chain, as shown in Fig. 12.

lVith the structure described when the operating member, which is shown in the shape of a channel iron but which may have somejother shape, pushed inone direction,

' for, instance, as shown by the arrows on Figs 1 and 12, the chains connected to the operating member are pushed outwardly through the shoes so as td force the sash open at thebottomwhen they are top-hung, the shoes oscillating to permit the chains to swing upwith the lowerends of the sash.

7 As the chain described can flex in butone direction when free and cannot flex in any direction between twofixed points and there fore is as strong as a channel iron'of similar cross section, great pressure may be applied 'to its inner end so that the sash will be surely swung open, and as the chainis fastened at its outer end to the sash and is held in a fixed position by theshoe, it cannot flex at any point between thesa'sh and the shoe, no matterhow great the'end pres sure which is beingexerted to push it out, or how great the resistance the sash offers to an opening movement. l/Vhen-the operat ing member is moved in the opposite, direc-- tion the chain is drawn in to the shoe and the sash is swung closed.

If desired-the operating member may, as shown in Fig. 13, .be a 'tube or shaft 23 1'0.- tarilymounted in brackets 24-, this shaft "being rotated .by any convenient means.

The shaft extends parallel with the swinging edges of the sash and opposite each has a sprocket wheel-25. Admin 26 connected witlrthe sash is passed over the sprocket and beneath a shoe 2'? which is hung on the shaft. Rotating the shaft causes the sprocket to push or pull the chains according to'the direction of rotationot the shaft, and thus open or close the sash; f

This mechanism can be located at the top or the-bottom of a series of windows .ac cording to how the sash are hung and may be constructed to-e'xtend a distance of many feet. along the siideof the building,depend ing, upon the" number of windows that it. is desired tocpen and close simultaneously,

and the sashbo'f thesewin dows must all be forced open and all be drawn tightly closed when" the operating member is? moved. The

parts of this mechanism are few and simple so that the structure will occupy but a little space and afford no material obstruction to access to the windows.

The invention claimed is;

1. The combination with a fixed casing and a window sash hinged at its upper edge to said casingso its loweredge swings outwardlyfor openingand inwardly for closinggof a metallic chain thatiis flexible in one direction only and is rigidwhen pushed or pulled longitudinally, said chain having one end secured to the outwardly swinging loweredge of the sash and its other end eX- tending inwardly therefrom across the easing, a' movable guide mounted inside of the casing and bearing on the back of and holding said chainso it cannot bendbetween the guide and the sash,v and means movably mounted inside of the-casing andconnected with the innerend ofthe chain and adapted when manipulated to push thechain through said guide outward across the casing and 'swing the window outward and to pull the chain inward across the casing through said guide and swing the window inward.
